Zusammenfassung: | A previous report from the Indian HIPEC registry showed acceptable early survival and morbidity in patients undergoing cytoreductive surgery (CRS) + / − hyperthermic intraperitoneal chemotherapy (HIPEC). The goal of this retrospective study was to evaluate the long-term outcomes in these patients. Three hundred seventy-four patients treated from December 2010 to December 2016 and enrolled in the Indian HIPEC registry were included. All patients had completed 5 years from the date of surgery. The 1-, 3-, 5- and 7-year progression-free (PFS) and overall survival (OS) and factors affecting these were evaluated. The histology was epithelial ovarian cancer in 209 (46.5%), pseudomyxoma peritonei (PMP) in 65 (17.3%) and colorectal cancer in 46 (12.9%) patients. The peritoneal cancer index (PCI) was ≥ 15 in 160 (42.8%). A completeness of cytoreduction (CC) score of 0/1 resection was obtained in 83% (CC-0–65%; CC-1–18%). HIPEC was performed in 59.2%. At a median, follow-up of 77 months (6–120 months), 243 (64.9%) patients developed recurrence, and 236 (63%) died of any cause; 138 (36.9%) were lost to follow-up. The median OS was 56 months (95% CI 53.42–61.07), and the median PFS was 28 months (95% CI 37.5–44.4). The 1-, 3-, 5- and 7-year OS was 97.6%, 63%, 37.7% and 24% respectively. The 1-, 3-, 5- and 7-year PFS was 84.8%, 36.5%, 27.3% and 22% respectively. The use of HIPEC (
p
= 0.03) and PMP of appendiceal origin (
p
= 0.01) was independent predictors of a longer OS. CRS + / − /HIPEC may achieve long-term survival in patients with PM from different primary sites in the Indian scenario. More prospective studies are needed to confirm these findings and identify factors influencing long-term survival. |
